Ensure password_encryption is set to scram-sha-256

高レベル 1自動yugabytedb

説明

The password_encryption parameter controls the algorithm used to hash passwords set by CREATE ROLE and ALTER ROLE statements. When set to md5 or on (which maps to md5), passwords are stored using MD5 which is cryptographically weak. Setting this to scram-sha-256 ensures passwords are stored using SCRAM-SHA-256, which provides strong security against offline password cracking attacks. Runs ysqlsh (add the YugabyteDB bin directory to PATH) against PGHOST/PGPORT (default 127.0.0.1:5433) as PGUSER (default yugabyte); supply the password through PGPASSWORD or ~/.pgpass.

修正方法

修正方法: ガイダンスまたは IaC パッチ

Set it with the YB-TServer GFlag --ysql_pg_conf_csv="password_encryption=scram-sha-256" on every YB-TServer, restart it and reset existing passwords so they are re-hashed with SCRAM.
